FLAHERTY & CRUMRINE PREFERRED INCOME OPPORTUNITY FUND

To the Shareholders of Flaherty & Crumrine Preferred Income Opportunity Fund:

Fiscal 2013 presented many challenges, but your Fund delivered respectable performance. Total return on net asset value (“NAV”)¹ was +2.8% for the fourth fiscal quarter² and +5.2% for the full fiscal year. As seen in the following table, over longer measurement periods, Fund performance has been excellent.

The Barclays Capital U.S. Aggregate Index is an unmanaged index considered representative of the U.S. investment grade, fixed-rate bond market.

(3)

The S&P 500 is a capitalization-weighted index of 500 common stocks. The index is designed to measure performance of the broad domestic economy through changes in the aggregate market value of 500 stocks representing all major industries.

Current performance may be lower or higher than the quoted past performance, which cannot guarantee future results. In addition, NAV performance will vary from market price performance, and you may have a taxable gain or loss when you sell your shares.

The table includes performance of two indices, Barclays Capital U.S. Aggregate and S&P 500 as proxies for bond and stock markets, respectively. While neither is a benchmark for Fund performance, they provide context for broad alternative-asset categories.

Total return based on market price of Fund shares was +2.5% for the quarter, as market price slightly outperformed NAV. This was a welcome change from a dramatic drop in market price relative to NAV during the two previous quarters. For fiscal 2013, total return on market price was a disappointing -4.4%.

On December 11^th, the Fund announced a special dividend of $0.073 per share, in addition to its regular monthly dividend of $0.073. In recent letters we have cautioned that issuer redemptions of older, higher-yielding securities or rising cost of leverage might put downward pressure on the Fund’s net investment income. The cost of leverage has remained low, and we have tried to be proactive in managing investments and leverage to produce high, sustainable income for shareholders. The proof of the pudding is in the eating—as of January 10, 2014 the current pre-tax monthly distribution rate on market price was 8.49%, and 59.1% of its 2013 dividends were characterized as qualified dividend income (with very favorable 15% and 20% tax rates).

¹	Following the methodology required by the SEC, total return assumes dividend reinvestment and includes income and principal change, plus the impact of the Fund’s leverage and expenses.

²	September 1—November 30, 2013

Our outlook for the preferred market is guardedly positive. We expect economic growth will accelerate gradually, but further increases in interest rates will be measured and monetary policy will remain accommodative for some time to come. Financial companies, the largest component of the preferred universe, are now healthier and more transparent than any time in memory. Against this backdrop, preferred securities should remain attractive for long-term investors.

Between early May and mid-September, intermediate and long-term interest rates rose significantly, as investors expressed concern over looming changes in monetary policy at the Federal Reserve (for Fed watchers, the so-called “tapering” of quantitative easing). Since then, these rates are little changed. The economy is on a path of recovery, but data suggest tepid and uneven growth. At present, we believe interest rates are consistent with moderate acceleration of economic activity in 2014, although our outlook for growth is slightly below consensus.

Short term interest rates are still hovering near zero (the key rates being fed funds and LIBOR). We monitor these closely as they drive the Fund’s cost of leverage. As the economy improves, these rates eventually will rise; however, we expect short-term interest rates to remain at or near current levels throughout 2014.

In addition to interest rates, regulatory developments remain center stage for the preferred market. A massive overhaul of rules and regulations overseeing banking and financial institutions is mostly complete, and implementation is well underway. We know with certainty preferred securities (in various forms) will continue to be a key component of capital for these industries. As rules are finalized, we gain a clearer sense about the types and amounts of preferred securities companies will likely utilize.

Many of the new rules are intended to keep companies from engaging in risky business practices that might lead to future crises. This will likely prove futile, as many risks are revealed only in hindsight. However, we believe the rules for reporting will result in greater transparency. Improved reporting makes the playing field more level, so the advantage will go to those who can make better decisions, rather than those receiving selective disclosure. And just maybe, markets will impose greater discipline on management. New rules also require financial companies to carry much more capital than before, which should make them more resilient in future downturns.

Our investment approach is simple to state and, hopefully, hard to replicate:

•

Produce in-depth, independent and objective credit research;

•

Dissect and analyze details of the securities in which we invest; and

•

Apply our long experience managing preferred securities portfolios to balance risks and returns revealed by those efforts.

It doesn’t always work perfectly, but it has worked pretty well for more than thirty years.

In the section below, we dig deeper into topics mentioned here as well as others of interest to shareholders. In addition, we encourage you to visit the Fund’s website, www.preferredincome.com for timely and important information.

DISCUSSION TOPICS

(Unaudited)

The Fund’s Portfolio Results and Components of Total Return on NAV

The table below reflects performance over both the recent six months and the Fund’s fiscal year of each element comprising total return for the Fund, namely: (a) investing in a portfolio of securities; (b) possibly hedging that portfolio of securities against significant increases in long-term interest rates; and (c) utilizing leverage to enhance returns to shareholders. Next, we compute the impact of the Fund’s operating expenses. All of the parts are summed to determine total return on NAV.

Components of PFO’s Total Return on NAV

for the Fiscal Year Ended November 30, 2013


		Six Months*			One Year
Total Return on Unleveraged Securities Portfolio (including principal change and income)			-0.9	%		4.7	%
Return from Interest Rate Hedging Strategy			N/A			N/A
Impact of Leverage (including leverage expense)			-0.4	%		1.8	%
Expenses (excluding leverage expense)			-0.7	%		-1.3	%
* Actual, not annualized.	Total Return on NAV		-2.0	%		5.2	%

For comparison, the following table displays returns over the same time periods on three indices compiled by Bank of America Merrill Lynch, reflecting various segments of the preferred securities market. Because these index returns exclude all expenses and the impact of leverage, they compare most directly to the top line in the Fund’s performance table above (Total Return on Unleveraged Securities Portfolio).]

Total Returns of Bank of America Merrill Lynch Preferred Securities Indices*

for Periods Ended November 30, 2013


	Six Months⁽¹⁾			One Year
BofA Merrill Lynch 8% Capped DRD Preferred Stock Index^SM		-6.5	%		-3.4	%
BofA Merrill Lynch 8% Capped Hybrid Preferred Securities Index^SM		-4.4	%		-1.7	%
BofA Merrill Lynch 8% Capped Corporate U.S. Capital Securities Index^SM		-1.1	%		4.3	%

The Bank of America Merrill Lynch 8% Capped DRD Preferred Stock Index^SM (P8D0) includes investment grade preferred securities issued by both corporations and government agencies that qualify for the corporate dividend received deduction with issuer concentration capped at a maximum of 8%. The Bank of America Merrill Lynch 8% Capped Hybrid Preferred Securities Index^SM (P8HO) includes taxable, fixed-rate, U.S. dollar-denominated investment-grade, preferred securities listed on a U.S. exchange with issuer concentration capped at 8%. The Bank of America Merrill Lynch 8% Capped Corporate U.S. Capital Securities Index^SM (C8CT) includes investment grade fixed rate or fixed-to-floating rate $1,000 par securities that receive some degree of equity credit from the rating agencies or their regulators with issuer concentration capped at a maximum of 8%. All index returns include interest and dividend income, but, unlike the Fund’s returns, are unmanaged and do not reflect any expenses.

⁽¹⁾

Actual, not annualized.

Over the past six-month and one-year time periods, the Fund’s (unleveraged) securities portfolio beat each of the three preferred market indices shown above. During fiscal 2013, the Fund’s total return on NAV also exceeded the returns on the indices, aided by the Fund’s use of leverage. While leverage can reduce returns during periods of adverse market conditions, during the recent fiscal year the low cost of leverage enhanced both income distributed by the Fund and its total return over the period.

Total Return on Market Price of Fund Shares

While our focus is primarily on managing the Fund’s investment portfolio, our shareholders’ actual return is comprised of the Fund’s monthly dividend payments plus changes in its market price. During the twelve-month period ending November 30, 2013, total return on market price of Fund shares declined by 4.4%.

Historically, the preferred securities market has experienced price volatility consistent with those of other fixed-income securities. However, since mid-2007 it has become clear that preferred-security valuations, including both Fund NAV and market price of its shares, can move dramatically when there is volatility in financial markets. The chart below contrasts the relative stability of the Fund’s earlier period with the more recent volatility in both its NAV and market price. Virtually all fixed-income asset classes experienced increased volatility over this period.

LOGO

In a more perfect world, the market price of Fund shares and its NAV, as shown in the above chart, would track more closely. If so, the resulting premium or discount of the Fund, calculated as the difference between these two inputs and expressed as a percentage, would remain relatively close to zero. However, as can be seen in the chart below, over the life of the Fund this often has not been the case. While the Fund began fiscal 2013 with its market price at a premium to NAV, by the end of the fiscal year the Fund was trading at a discount, and, as a result, the total return earned on market price trailed the total return on NAV shown in the table above.

Although divergence between NAV and market price of a closed-end fund is generally driven by supply/demand imbalances affecting its market price, we can only speculate about why the relationship between the Fund’s market price and NAV hasn’t been closer.

LOGO

Based on a closing price of $10.08 on December 31^st, the current annualized yield on market price of Fund shares (assuming its current monthly distribution of $0.073 does not change) is 8.69%. In our opinion, this distribution rate measures up favorably with most comparable fixed-income investment opportunities.

Preferred Market Conditions

Three factors dominated the preferred market in 2013—credit quality, market size and interest rates. Since the depths of the financial crisis in 2008/09, improving credit quality and contraction in market size have boosted the preferred market. More recently, the market has been battered by concerns over rising interest rates as the economy strengthens.

We focus on companies in financial industries such as banking and insurance because they are the dominant issuers of preferred securities, and of course comprise the bulk of the Fund’s investments. The nature of preferred capital, subordinated to debt but not dilutive like equity, makes it particularly useful to regulated companies in these more-leveraged industries.

The financial crisis exposed unwise and risky practices at many financial companies, with several getting swallowed up or shut down. But well-managed companies also paid a steep price for the sins of the few. In the U.S., the Dodd-Frank Financial Regulatory Reform Bill, the most sweeping regulatory change in decades, dramatically altered the way all financial companies operate. Similar changes are being made abroad. The new rules restrict certain risky activities and force companies to have more “skin in the game.” In our view, these changes (along with increased transparency) have improved fundamental credit quality.

Among other things, financial companies must alter the amount and tenor of preferred capital they issue. Most “trust preferred” issues have been redeemed, frequently replaced with new issues structured to satisfy requirements of the new rules. As is often the case, what’s old is new again—traditional perpetual, non-cumulative preferred stock is once again being issued by domestic banks. Many of these new issues fit nicely in the Fund’s portfolio.

Non-US banks have been utilizing a newer structure, generically-called contingent-capital securities (“CoCo”). These typically mandate principal be written down or wiped out if certain financial thresholds are breeched. So far, we have adopted a wait and see attitude on CoCo securities; a repeat of the financial crisis, real or perceived, may impact this structure more harshly than others.

The jump in intermediate and long term interest rates this the past summer resulted in price declines for most fixed-income securities, including preferreds. Although interest rates have been relatively stable in recent months, some interesting anomalies have developed in the preferred market.

With equity markets at or near all-time highs, some investors chose to take money off the table and sell appreciated stocks. For some, realizing gains creates tax liabilities. Strategies to reduce this tax bill usually start with realizing losses, if available, on other portfolio holdings. We believe the poorer performing preferred securities were targeted for tax-loss selling, and in turn, lower prices led to more selling. This is nothing new, a phenomenon we’ve seen before; we’ll do our best to take advantage of the opportunity.

Monthly Distributions to Fund Shareholders

Fiscal-year 2013 presented many challenges related to interest rates and valuations of preferred securities, but income continues to be a very bright spot for the Fund. Our regular readers will recall our description of near-ideal conditions for generating high current income—attractive yields on preferred securities owned by the Fund combined with historically low rates for leverage used in our strategy.

The Fund once again made a special distribution of income in December. For calendar year 2013, total distributions to shareholders (including the special distribution) were 8.3% higher than the sum of ordinary monthly distributions during the year.

We have warned in recent years that low interest rates would have an impact on top-line income of the Fund, and it has. A number of higher-coupon securities have been redeemed by issuers, often times refinanced with new securities paying lower coupons. This trend was in full force during the first half of the year. If there is a silver lining to market weakness that began in early summer, it is that higher rates and wider spreads all but stopped issuer redemptions during the second half of the year. Market weakness also allowed the Fund to reallocate some of the portfolio to take advantage of higher yields.

Although reinvestment risk is always part of owning preferred securities, the reinvestment process related to trust preferred securities is essentially complete. Going forward, reinvestment risk will be a function of more traditional factors—interest rates and spreads on preferred securities. The Fund still owns certain securities with relatively high coupons, and those securities may be subject to redemption over the coming year or two. However, we factored in our best estimates of redemptions and reinvestment rates and concluded there was no reason to modify the existing distribution rate to shareholders.

When it comes to projecting income available to shareholders in future years, the elephant in the room is the expected cost of leverage. The use of leverage is an important part of the Fund’s strategy for producing high current income, and we could not produce the Fund’s current level of income without it. We expect leverage costs—which for the Fund are currently 3-month LIBOR +0.75%, reset quarterly—will remain low into 2015, and maybe longer, given our economic outlook and guidance from the Federal Reserve. That said, any early increase in short-term rates would have a negative impact on distributable income.

Some might ask: if you expect the cost of leverage to increase, why not remove leverage from the Fund? The answer is twofold. First, so long as the cost of leverage is below income earned on preferred securities—which has almost always been the case—income available to shareholders will be higher with

leverage than it would be without leverage. Second, following the same logic, removing leverage today would result in a material reduction in the current dividend rate given the current wide spread between yields on preferred securities and cost of leverage. So even if leverage costs increase, benefits to distributable income over time are still substantial.

We want shareholders to understand the Fund’s strategy for producing high current income, including risk factors that affect distribution rates—both positive and negative. We believe the Fund’s strategy of investing in preferred securities and using leverage in an efficient manner will continue to produce a competitive distribution rate for shareholders.

Economic Conditions

The U.S. economy strengthened in the second half of the year and appears to be on solid footing heading into 2014. Inflation-adjusted gross domestic product (real GDP) should post about 3% annualized growth in 2013’s second half after rising just 1.8% in the first half. Private economists forecast real GDP growth of 2.6% in 2014; the Federal Reserve is more optimistic, expecting 2.8-3.2% growth.

The economic outlook remains mixed but mostly improving. Job gains have accelerated in recent months, and wages are slowly picking up. However, consumers continue to deleverage and pay down debt, restraining consumption. Housing remains a bright spot that should add to economic growth despite higher mortgage rates. Business investment should improve a bit, and government spending should be less of a drag on growth in 2014 than it was last year. Finally, global economic growth is improving, although recovery remains fragile in Europe and a number of developing countries.

On balance, we expect 2.2-2.5% real GDP growth in 2014, slower than the Fed’s relatively optimistic outlook. For monetary policy, moderate growth means no rate hikes and only gradual reductions in securities purchases this year—an outlook that appears largely incorporated into current prices. Long-term interest rates should drift higher, but further rate increases are likely to be modest. We are mindful, however, that there may be periodic “growth scares” that could push rates upward quickly; investors should be prepared for volatility in 2014.

More positively, credit conditions continue to improve. A growing economy, lower leverage and stronger balance sheets mean better fundamental credit quality for preferred securities, and we foresee this improvement continuing for some time to come. We expect yield spreads on preferred securities to narrow over time.

Putting this together, we expect returns on preferred securities to be “coupon” or “coupon minus” in 2014 rather than “coupon plus” experienced from 2009-2012. However, despite this more challenging market environment, we believe preferred securities remain attractive relative to short-duration bond alternatives, and investors should return to them as fears of rapidly rising interest rates subside.

Hedging Long-Term Interest Rate Risk

As long-time shareholders know, the Fund suspended its long-term interest rate hedging program as the financial crisis intensified in the autumn of 2008. There were three principal reasons why we suspended the program. First, correlation between preferred securities and the Fund’s hedging instruments (Treasury bond futures, interest rate swaps, and options on both) switched from positive to negative during the financial crisis. Second, hedging cost rose dramatically, as the yield curve steepened and options prices rose sharply. Finally, preferred securities were exceptionally cheap and likely to offer higher returns to shareholders than investments in hedge instruments. Adding them up, we believed that hedging did not make sense.

Until spring of 2013, that judgment was correct. Preferred securities’ prices generally rose and were at best loosely correlated to Treasuries. Beginning in early May, however, correlation increased substantially. The benchmark 30-year Treasury bond’s yield increased from a low of 2.82% to nearly 4% as of December 31, 2013, and preferred securities traded down by a similar amount.

With positive correlation reestablished between long-term Treasuries and preferred securities, we can be reasonably confident that an interest-rate hedging strategy would in fact be a hedge rather than just a bet on higher Treasury rates. However, the cost of hedging remains high. The Treasury yield curve is steep (approaching 400 basis points from overnight to 30-years), and option prices are also high. Given our outlook for only moderate economic growth, we believe markets have priced in a larger increase in interest rates than we are likely to experience. We may be wrong about that, but rates would have to rise quite substantially from current levels for hedging to be profitable, given what is already priced into today’s yield curve.

Finally, we think yields on preferred securities in a range of 6.75-7.25% (with outliers on either side) are attractive compared to a 4% long-bond yield—and even compared to Treasuries at 5%, if and when they get there. Spreads of 300 basis points over Treasuries provide substantial protection against higher rates.

We are monitoring hedge alternatives closely and will consider hedging again if circumstances warrant it. For now, we think costs of hedging the impact of changes in long-term interest rates on the Fund’s preferred securities portfolio outweigh any benefits.

Federal Tax Advantages of 2013 Calendar Year Distributions

In calendar year 2013, approximately 59.1% of distributions made by the Fund was eligible for treatment as qualified dividend income, or QDI. For taxpayers in the 15% marginal tax bracket, QDI is taxed by the federal government at 0% instead of an individual’s ordinary income tax rate; for taxpayers in the 25%-35% marginal tax brackets, QDI is taxed at 15%; and for taxpayers in the 39.6% marginal tax bracket, QDI is taxed at 20%.

For an individual in the 28% marginal tax bracket, this means that the Fund’s total distributions will only be taxed at a blended 20.3% rate versus the 28% rate which would apply to distributions by a fund investing in traditional corporate bonds. This tax advantage means that, all other things being equal, such an individual who held 100 shares of Common Stock of the Fund for the calendar year would have had to receive approximately $97 in distributions from a fully-taxable bond fund to net the same after-tax amount as the $87.00 in distributions paid by the Fund.

For detailed information about tax treatment of particular distributions received from the Fund, please see the Form 1099 you receive from either the Fund or your broker.

Corporate shareholders also receive a federal tax benefit from the 23.5% distributions that were eligible for the inter-corporate dividends received deduction, or DRD.

It is important to remember that composition of the portfolio and income distributions can change from one year to the next, and that the QDI or DRD portions of 2014’s distributions may not be the same (or even similar) to 2013.

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS

1.	Organization

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated (the “Fund”) was incorporated as a Maryland corporation on December 10, 1991, and commenced operations on February 13, 1992 as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”). The Fund’s investment objective is to provide its common shareholders with high current income consistent with the preservation of capital.

2.	Significant Accounting Policies

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. The preparation of the financial statements is in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) and requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities in the financial statements and the reported amounts of increases and decreases in net assets from operations during the reporting period. Actual results could differ from those estimates.

Portfolio valuation: The net asset value of the Fund’s Common Stock is determined by the Fund’s Administrator no less frequently than on the last business day of each week and month in accordance with the policies and procedures approved by the Board of Directors of the Fund. It is determined by dividing the value of the Fund’s net assets available to Common Stock by the number of shares of Common Stock outstanding. The value of the Fund’s net assets available to Common Stock is deemed to equal the value of the Fund’s total assets less (i) the Fund’s liabilities and (ii) the aggregate liquidation value of any outstanding preferred stock.

The Fund’s preferred and debt securities are valued on the basis of current market quotations provided by independent pricing services or dealers approved by the Board of Directors of the Fund. Each quotation is based on the mean of the bid and asked prices of a security. In determining the value of a particular preferred or debt security, a pricing service or dealer may use information with respect to transactions in such investments, quotations, market transactions in comparable investments, various relationships observed in the market between investments, and/or calculated yield measures based on valuation technology commonly employed in the market for such investments. Common stocks that are traded on stock exchanges are valued at the last sale price or official close price on the exchange, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available mean price. Futures contracts and option contracts on futures contracts are valued on the basis of the settlement price for such contracts on the primary exchange on which they trade. Investments in over-the-counter derivative instruments, such as interest rate swaps and options thereon (“swaptions”), are valued using prices supplied by a pricing service, or if such prices are unavailable, prices provided by a single broker or dealer that is not the counterparty or, if no such prices are available, at a price at which the counterparty to the contract would repurchase the instrument or terminate the contract. Investments for which market quotations are not readily available or for which management determines that the prices are not reflective of current market conditions are valued at fair value as determined in good faith by or under the direction of the Board of Directors of the Fund, including reference to valuations of other securities which are comparable in quality, maturity and type.

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS (Continued)

Investments in money market instruments and all debt and preferred securities which mature in 60 days or less are valued at amortized cost. Investments in money market funds are valued at the net asset value of such funds.

Fair Value Measurements: The Fund has performed an analysis of all existing investments and derivative instruments to determine the significance and character of all inputs to their fair value determination. The levels of fair value inputs used to measure the Fund’s investments are characterized into a fair value hierarchy. Where inputs for an asset or liability fall into more than one level in the fair value hierarchy, the investment is classified in its entirety based on the lowest level input that is significant to that investment’s valuation. The three levels of the fair value hierarchy are described below:


•	Level 1 –	quoted prices in active markets for identical securities

•	Level 2 –	other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

•	Level 3 –	significant unobservable inputs (including the Fund’s own assumptions in determining the fair value of investments)

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. Transfers in and out of levels are recognized at market value at the end of the period. A summary of the inputs used to value the Fund’s investments as of November 30, 2013 is as follows:


	Total Value at November 30, 2013		Level 1 Quoted Price		Level 2 Significant Observable Inputs		Level 3 Significant Unobservable Inputs

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS (Continued)

During the reporting period, there were no transfers into Level 1 from Level 2. During the reporting period, securities with an aggregate market value of $2,813,126 were transferred into Level 2 from Level 1. The securities were transferred because of a reduction in the amount of observable market data, resulting from: a decrease in market activity for the securities, reduced availability of quoted prices for the securities, or de-listing of securities from a national securities exchange that resulted in a material decrease in activity.

The fair values of the Fund’s investments are generally based on market information and quotes received from brokers or independent pricing services—approved by the Board and unaffiliated with the Adviser. To assess the continuing appropriateness of security valuations, management, in consultation with the Adviser, regularly compares current prices to prior prices, prices across comparable securities, actual sale prices for securities in the Fund’s portfolio, and market information obtained by the Adviser as a function of being an active participant in the markets.

Securities with quotes that are based on actual trades or actionable bids and offers with a sufficient level of activity on or near the measurement date are classified as Level 1. Securities that are priced using quotes derived from implied values, indicative bids and offers, or a limited number of actual trades—or the same information for securities that are similar in many respects to those being valued—are classified as Level 2. If market information is not available for securities being valued, or materially-comparable securities, then those securities are classified as Level 3. In considering market information, management evaluates changes in liquidity, willingness of a broker to execute at the quoted price, the depth and consistency of prices from pricing services, and the existence of observable trades in the market.

The following is a reconciliation of Level 3 investments for which significant unobservable inputs were used to determine fair value:


	Preferred Securities
	Total Investments			Banking
Balance as of 11/30/12	$	9,000		$	9,000
Accrued discounts/premiums		—			—
Realized gain/(loss)		(4,462,500	)		(4,462,500	)

Purchases		—			—
Sales		—			—
Transfer in		—			—
Transfer out		—			—
Balance as of 11/30/13	$	6,750		$	6,750

For the year ended November 30, 2013, total change in unrealized gain/(loss) on Level 3 securities still held at period-end and included in the change in net assets was $0. Total unrealized gain/(loss) for all securities (including Level 1 and Level 2) can be found on the accompanying Statement of Operations.

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

The following table summarizes the valuation techniques used and unobservable inputs developed to determine the fair value of Level 3 investments:

Bankruptcy recovery

Credit/Structure-specific
recovery

0.00% - 0.50% (0.15%)

The significant unobservable inputs used in the fair value measurement technique for bankruptcy recovery are based on recovery analysis that is specific to the security being valued, including the level of subordination and structural features of the security, and the current status of any bankruptcy or liquidation proceedings. Observable market trades in bankruptcy claims are utilized by management, when available, to assess the appropriateness of valuations, although the frequency of trading depends on the specific credit and seniority of the claim. Expected recoveries in bankruptcy by security type and industry do not tend to deviate much from historical recovery rates, which are very low (sometimes zero) for preferred securities and more moderate for senior debt. Significant changes in these inputs would result in a significantly higher or lower fair value measurement.

Securities transactions and investment income: Securities transactions are recorded as of the trade date. Realized gains and losses from securities sold are recorded on the specific identified cost basis. Dividend income is recorded on ex-dividend dates. Interest income is recorded on the accrual basis. The Fund also amortizes premiums and accretes discounts on fixed income securities using the effective yield method.

Options: Purchases of options are recorded as an investment, the value of which is marked-to-market at each valuation date. When the Fund enters into a closing sale transaction, the Fund will record a gain or loss depending on the difference between the purchase and sale price.

When the Fund writes an option, an amount equal to the premium received by the Fund is recorded as a liability, the value of which is marked-to-market at each valuation date. When a written option expires, the Fund realizes a gain equal to the amount of the premium originally received. When the Fund enters into a closing purchase transaction, the Fund realizes a gain (or loss if the cost of the closing purchase transaction exceeds the premium received when the option was written) without regard to any unrealized gain or loss on the underlying security, and the liability related to such option is eliminated. When a call option is exercised, the Fund realizes a gain or loss from the sale of the underlying security and the proceeds from such sale are increased by the amount of the premium originally received. When a put option is exercised, the amount of the premium originally received will reduce the cost of the security which the Fund purchased upon exercise.

Repurchase agreements: The Fund may engage in repurchase agreement transactions. The Adviser reviews and approves the eligibility of the banks and dealers with which the Fund may enter into repurchase agreement transactions. The value of the collateral underlying such transactions is at least equal at all times to the total amount of the repurchase obligations, including interest. The Fund maintains possession of the collateral through its custodian and, in the event of counterparty default, the Fund has the right to use the

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS (Continued)

collateral to offset losses incurred. There is the possibility of loss to the Fund in the event the Fund is delayed or prevented from exercising its rights to dispose of the collateral securities.

Federal income taxes: The Fund intends to continue to qualify as a regulated investment company by complying with the requirements under subchapter M of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies and intends to distribute substantially all of its taxable net investment income to its shareholders. Therefore, no federal income tax provision is required.

Management has analyzed the Fund’s tax positions taken on federal income tax returns for all open tax years (November 30, 2013, 2012 and 2011), and has concluded that no provision for federal income tax is required in the Fund’s financial statements. The Fund’s major tax jurisdictions are federal and California. The Fund’s federal and state income and federal excise tax returns for tax years for which the applicable statutes of limitations have not expired are subject to examination by the Internal Revenue Service and state departments of revenue.

Dividends and distributions to shareholders: The Fund expects to declare dividends on a monthly basis to shareholders of Common Stock (“Shareholders”). Distributions to Shareholders are recorded on the ex-dividend date. Any net realized short-term capital gains will be distributed to Shareholders at least annually. Any net realized long-term capital gains may be distributed to Shareholders at least annually or may be retained by the Fund as determined by the Fund’s Board of Directors. Capital gains retained by the Fund are subject to tax at the capital gains corporate tax rate. Subject to the Fund qualifying as a regulated investment company, any taxes paid by the Fund on such net realized long-term capital gains may be used by the Fund’s Shareholders as a credit against their own tax liabilities. The Fund may pay distributions in excess of the Fund’s net investment company taxable income and this excess would be a tax-free return of capital distributed from the Fund’s assets.

Income and capital gain distributions are determined and characterized in accordance with income tax regulations which may differ from U.S. GAAP. These differences are primarily due to (1) differing treatments of income and gains on various investment securities held by the Fund, including timing differences, (2) the attribution of expenses against certain components of taxable investment income, and (3) federal regulations requiring proportionate allocation of income and gains to all classes of shareholders.

Distributions from net realized gains for book purposes may include short-term capital gains, which are included as ordinary income for tax purposes, and may exclude amortization of premium and discount on certain fixed income securities, which are not reflected in ordinary income for tax purposes. The tax character of distributions paid during 2013 and 2012 was as follows:


	Distributions paid in fiscal year 2013		Distributions paid in fiscal year 2012
	Ordinary Income	Long-Term Capital Gains	Ordinary Income	Long-Term Capital Gains

Common Stock	$12,175,696	$0	$11,554,180	$0

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS (Continued)

As of November 30, 2013, the components of distributable earnings (i.e., ordinary income and capital gain/loss) available to Shareholders, on a tax basis, were as follows:

The composition of the Fund’s accumulated realized capital losses is indicated below. These losses may be carried forward and offset against future capital gains through the dates listed below.


2017		No Expiration Short Term*	No Expiration Long Term*	Total
$	13,753,371	$0	$0	$	13,753,371

Under the Regulated Investment Company Modernization Act of 2010 (“Modernization Act”), the Fund is permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 indefinitely. However, any losses incurred during those future taxable years must be utilized prior to the losses incurred in pre-enactment taxable years. As a result, pre-enactment capital loss carryforwards may be more likely to expire unused. Additionally, post-enactment capital losses that are carried forward will retain their character as either short-term or long-term capital losses rather than being considered all short-term under previous law.

During the year ended November 30, 2013, the Fund utilized $5,846,694 and $9,019 of capital losses expiring in 2016 and 2017, respectively.

Reclassification of accounts: During the year ended November 30, 2013, reclassifications were made in the Fund’s capital accounts to report these balances on a tax basis, excluding temporary differences, as of November 30, 2013. Additional adjustments may be required in subsequent reporting periods. These reclassifications have no impact on the net asset value of the Fund. The calculation of net investment income per share in the financial highlights excludes these adjustments. Below are the reclassifications:


Paid-in Capital	Undistributed Net Investment Income	Accumulated Net Realized Gain on Investments

$9,346	$98,302	$(107,648)

Excise tax: The Internal Revenue Code of 1986, as amended, imposes a 4% nondeductible excise tax on the Fund to the extent the Fund does not distribute by the end of any calendar year at least (1) 98% of the sum of its net investment income for that year and 98.2% of its capital gains (both long-term and short term) for its fiscal year and (2) certain undistributed amounts from previous years. The Fund is subject to a payment of an estimated $2,480 of federal excise taxes attributed to calendar year 2013. The Fund paid $960 of federal excise taxes attributable to calendar year 2012 in March 2013.

3.	Derivative Instruments

The Fund intends to use derivatives primarily to economically hedge against risks in the portfolio, namely interest rate risk and credit risk. Historically, the Fund has used options on treasury futures contracts for the purpose of economically hedging against a significant increase in long-term interest rates. When the strategy has been employed, the Fund would purchase put options on treasury futures contracts that would increase in value if long-term interest rates increased significantly, offsetting some of the related decline in

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS (Continued)

portfolio asset values. The Fund has also purchased and written call options on treasury futures contracts to supplement the put option strategy and also to reduce the overall cost of the interest rate hedge (by earning premiums from the net sale of call options).

The Fund has the authority to use other derivatives for hedging or to increase expected return, but has not employed any of these derivatives to-date and does not anticipate broad use of these derivatives in the near future (although this may change without advance notice). Other approved derivatives strategies include: buying and selling credit default swaps, interest rate swaps and options thereon (swaptions), and options on securities. Accounting policies for specific derivatives, including the location of these items in the financial statements, are included in Note 2 as appropriate. No assurance can be given that such use of derivatives will achieve their desired purposes or, in the case of hedging, will result in an overall reduction of risk to the Fund.

The Fund did not use any derivatives during the fiscal years ended November 30, 2013 and November 30, 2012.

Options on Financial Futures Contracts: When the interest rate hedging strategy is employed, the Fund intends to use options on financial futures contracts in much the same way as described above. The risk associated with purchasing options, and therefore the maximum loss the Fund would incur, is limited to the purchase price originally paid. The risk in writing a call option is that the Fund may forego the opportunity for profit if the market price of the underlying security increases and the option is exercised. The risk in writing a put option is that the Fund may incur a loss if the market price of the underlying security decreases and the option is exercised.

4.	Investment Advisory Fee, Administration Fee, Transfer Agent Fee, Custodian Fee, Directors’ Fees and Chief Compliance Officer Fee

Flaherty & Crumrine Incorporated (the “Adviser”) serves as the Fund’s investment adviser. The Fund pays the Adviser a monthly fee at an annual rate of 0.625% of the Fund’s average monthly total managed assets up to $100 million and 0.50% of the Fund’s average monthly total managed assets of $100 million or more.

For purposes of calculating the fees payable to the Adviser, Administrator and Custodian, the Fund’s total managed assets means the total assets of the Fund (including any assets attributable to the Fund’s preferred stock that may be outstanding or otherwise attributable to the use of leverage) minus the sum of accrued liabilities (other than debt, if any, representing financial leverage). For purposes of determining total managed assets, the liquidation preference of any outstanding preferred shares issued by the Fund is not treated as a liability.

BNY Mellon Investment Servicing (US) Inc. (“BNY Mellon”) serves as the Fund’s administrator (the “Administrator”). As Administrator, BNY Mellon calculates the net asset value of the Fund’s shares attributable to Common Stock and generally assists in all aspects of the Fund’s administration and operation. As compensation for BNY Mellon’s services as Administrator, the Fund pays BNY Mellon a monthly fee at an annual rate of 0.10% of the first $200 million of the Fund’s average weekly total managed assets, 0.04% of the next $300 million of the Fund’s average weekly total managed assets, 0.03% of the next $500 million of the

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS (Continued)

Fund’s average weekly total managed assets and 0.02% of the Fund’s average weekly total managed assets above $1 billion.

BNY Mellon also serves as the Fund’s Common Stock dividend-paying agent and registrar (the “Transfer Agent”). Effective April 1, 2013, as compensation for BNY Mellon’s services as Transfer Agent, the Fund pays BNY Mellon a monthly fee in the amount of $1,500. Prior to April 1, 2013, the Fund paid BNY Mellon a fee at an annual rate of 0.02% of the first $150 million of the Fund’s average weekly net assets attributable to Common Stock, 0.0075% of the next $350 million of the Fund’s average weekly net assets attributable to Common Stock, and 0.0025% of the Fund’s average weekly net assets attributable to Common Stock above $500 million, plus certain out of pocket expenses. For the purpose of calculating such fee, the Fund’s average weekly net assets attributable to Common Stock are deemed to be the average weekly value of the Fund’s total assets minus the sum of the Fund’s liabilities. For this calculation, the Fund’s liabilities are deemed to include the aggregate liquidation preference of any outstanding preferred shares and the loan principal balance.

The Bank of New York Mellon (the “Custodian”) serves as the Fund’s Custodian.

6.	Common Stock

At November 30, 2013, 240,000,000 shares of $0.01 par value Common Stock were authorized.

Common Stock transactions were as follows:


	Year Ended 11/30/13				Year Ended 11/30/12
	Shares		Amount		Shares		Amount
Shares issued under the Dividend Reinvestment and Cash Purchase Plan.		93,286	$	1,068,603		113,337	$	1,242,529

7.	Preferred Stock

The Fund’s Articles of Incorporation authorize the issuance of up to 10,000,000 shares of $0.01 par value preferred stock. The Fund does not currently have any issued and outstanding shares of preferred stock.

8.	Committed Financing Agreement

The Fund has entered into a committed financing agreement (“Financing Agreement”) that allows the Fund to borrow on a secured basis, which the Fund uses in the normal course of business as financial leverage. Such leveraging tends to magnify both the risks and opportunities to Shareholders. The Financing Agreement has been amended from time to time to allow for changes in the committed amount. As of November 30, 2013, the committed amount, and amount borrowed, under the Financing Agreement was $70.2 million.

The lender charges an annualized rate of 0.65% on the undrawn (committed) balance, and three-month LIBOR (reset quarterly) plus 0.75% on the drawn (borrowed) balance. For the year ended November 30, 2013, the daily weighted average annualized interest rate on the drawn balance was 1.04% and the average daily loan balance was $69,338,356. LIBOR rates may vary in a manner unrelated to the income received on the Fund’s assets, which could have either a beneficial or detrimental impact on net investment income and gains available to Shareholders.

The Fund is required to meet certain asset coverage requirements under the Financing Agreement and under the 1940 Act. In accordance with the asset coverage requirements, at least two-thirds of the Fund’s assets are expected to be pledged as collateral assuming the full committed amount is drawn. Securities pledged as collateral are identified in the portfolio of investments. If the Fund fails to meet these requirements, or maintain other financial covenants required under the Financing Agreement, the Fund may be required to repay immediately, in part or in full, the amount borrowed under the Financing Agreement. Additionally, failure to meet the foregoing requirements or covenants could restrict the Fund’s ability to pay dividends to Shareholders and could necessitate sales of portfolio securities at inopportune times. The Financing Agreement has no stated maturity, but may be terminated by either party without cause with six months’ advance notice.

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS (Continued)

Under the terms of the Financing Agreement, the lender has the ability to borrow a portion of the securities pledged as collateral against the loan (“Rehypothecated Securities”), subject to certain limits. The Fund receives a fee from the lender in connection with any Rehypothecated Securities. The Fund may recall any Rehypothecated Security at any time and the lender is required to return the security in a timely fashion. In the event the lender does not return the security, the Fund will have the right to, among other things, apply and set off an amount equal to 100% of the then-current fair market value of such Rehypothecated Securities against any loan amounts owed to the lender under the Financing Agreement. Rehypothecated Securities are marked-to-market daily and adjusted as necessary so the value of all Rehypothecated Securities does not exceed 100% of the loan amount under the Financing Agreement. The Fund will continue to earn and receive all dividends, interest, and other distributions on Rehypothecated Securities. Rehypothecated Securities are identified in the Portfolio of Investments listing and fees earned from rehypothecation are included in the Statement of Operations.

9.	Portfolio Investments, Concentration and Investment Quality

The Fund invests primarily in a diversified portfolio of preferred securities. This includes traditional preferred stocks eligible for the inter-corporate dividends received deduction (“DRD”) and fully taxable preferred securities. Under normal market conditions, at least 80% of the Fund’s net assets will be invested in preferred securities. Also, under normal market conditions, the Fund invests at least 25% of its total assets in the financial services sector. For purposes of the financial services sector concentration policy, a company is within the financial services sector if it derives at least 50% of its revenue from providing financial services. The Fund’s portfolio may therefore be subject to greater risk and market fluctuation than a portfolio of securities representing a broader range of investment alternatives.

The Fund may invest up to 25% of its assets at the time of purchase in securities rated below investment grade by all of Moody’s, S&P and Fitch, provided that (a) such securities are rated at least “Ba3” by Moody’s, “BB-” by S&P, or “BB-” by Fitch or (b) such securities are issued by an issuer having an outstanding class of senior debt rated investment grade by any one of Moody’s, S&P, or Fitch at the time of purchase. Thus, the Fund may invest in securities rated below “Ba3” by Moody’s, “BB-” by S&P and “BB-” by Fitch if the issuer has investment grade senior debt outstanding. In addition, the Fund may invest in unrated securities that the Fund’s investment adviser deems to be comparable in quality to rated issues in which the Fund is authorized to invest.

The Fund may invest up to 15% of its assets in common stocks and, under normal market conditions, up to 20% of its assets in debt securities. Certain of its investments in hybrid, i.e., fully taxable, preferred securities will be subject to the foregoing 20% limitation to the extent that, in the opinion of the Adviser, such investments are deemed to be debt-like in key characteristics. Typically, a security will not be considered debt-like (a) if an issuer can defer payment of income for eighteen months or more without triggering an event of default and (b) if such issue is a junior and fully subordinated liability of an issuer or its ultimate guarantor.

In addition to foreign money market securities, the Fund may invest up to 30% of its total assets in the securities of companies organized or having their principal place of business outside the United States. All foreign securities held by the Fund will be denominated in U.S. dollars.

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

NOTES TO FINANCIAL STATEMENTS (Continued)

The Fund may employ certain investment techniques in accordance with its fundamental investment policies. These may include the use of when-issued and delayed delivery transactions. Securities purchased or sold on a when-issued or delayed delivery basis may be settled within 45 days after the date of the transaction. The Fund may also enter into transactions, in accordance with its investment policies, involving short sales of securities and purchases of securities on margin. Such transactions may expose the Fund to credit and market valuation risk greater than that associated with regular trade settlement procedures.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Shareholders and Board of Directors of

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

We have audited the accompanying statement of assets and liabilities of Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated, including the portfolio of investments, as of November 30, 2013, and the related statement of operations and cash flows for the year then ended, the statements of changes in net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended. These financial statements and financial highlights are the responsibility of the Fund’s management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of November 30, 2013, by correspondence with the custodian. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated as of November 30, 2013, the results of its operations and its cash flows for the year then ended, the changes in its net assets for each of the years in the two-year period then ended, and the financial highlights for each of the years in the five-year period then ended, in conformity with accounting principles generally accepted in the United States of America.

Dividend Reinvestment and Cash Purchase Plan

Under the Fund’s Dividend Reinvestment and Cash Purchase Plan (the “Plan”), a shareholder whose Common Stock is registered in his or her own name will have all distributions reinvested automatically by BNY Mellon as agent under the Plan, unless the shareholder elects to receive cash. Registered shareholders may elect to receive cash by contacting BNY Mellon at the number provided below. If shares are registered in the name of a broker-dealer or other nominee (that is, in “street name”) and the broker or nominee participates in the Plan, distributions may be reinvested by the broker or nominee in additional shares under the Plan, unless the shareholder elects to receive distributions in cash. Shareholders may elect to receive cash by contacting their broker or nominee. A shareholder who holds Common Stock registered in the name of a broker or other nominee may not be able to transfer the Common Stock to another broker or nominee and continue to participate in the Plan. Investors who own Common Stock registered in street name should consult their broker or nominee for details regarding reinvestment.

The number of shares of Common Stock distributed to participants in the Plan in lieu of a cash dividend is determined in the following manner. Whenever the market price per share of the Fund’s Common Stock is equal to or exceeds the net asset value per share on the valuation date, participants in the Plan will be issued new shares valued at the higher of net asset value or 95% of the then current market value. Otherwise, BNY Mellon will buy shares of the Fund’s Common Stock in the open market, on the New York Stock Exchange (“NYSE”) or elsewhere, on or shortly after the payment date of the dividend or distribution and continuing until the ex-dividend date of the Fund’s next distribution to holders of the Common Stock or until it has expended for such purchases all of the cash that would otherwise be payable to the participants. The number of purchased shares that will then be credited to the participants’ accounts will be based on the average per share purchase price of the shares so purchased, including brokerage commissions. If BNY Mellon commences purchases in the open market and the then current market price of the shares (plus any estimated brokerage commissions) subsequently exceeds their net asset value most recently determined before the completion of the purchases, BNY Mellon will attempt to terminate purchases in the open market and cause the Fund to issue the remaining dividend or distribution in shares. In this case, the number of shares received by the participant will be based on the weighted average of prices paid for shares purchased in the open market and the price at which the Fund issues the remaining shares. These remaining shares will be issued by the Fund at the higher of net asset value or 95% of the then current market value.

Plan participants are not subject to any charge for reinvesting dividends or capital gains distributions. Each Plan participant will, however, bear a proportionate share of brokerage commissions incurred with respect to BNY Mellon’s open market purchases in connection with the reinvestment of dividends or capital gains distributions. For the year ended November 30, 2013, $1,233 in brokerage commissions were incurred.

The automatic reinvestment of dividends and capital gains distributions will not relieve Plan participants of any income tax that may be payable on the dividends or capital gains distributions. A participant in the Plan will be treated for Federal income tax purposes as having received, on the dividend payment date, a dividend or distribution in an amount equal to the cash that the participant could have received instead of shares.

Flaherty & Crumrine Preferred Income Opportunity Fund Incorporated

ADDITIONAL INFORMATION (Unaudited) (Continued)

In addition to acquiring shares of Common Stock through the reinvestment of cash dividends and distributions, a shareholder may invest any further amounts from $100 to $3,000 semi-annually at the then current market price in shares purchased through the Plan. Such semi-annual investments are subject to any brokerage commission charges incurred by BNY Mellon under the Plan.

A shareholder whose Common Stock is registered in his or her own name may terminate participation in the Plan at any time by notifying BNY Mellon in writing, by completing the form on the back of the Plan account statement and forwarding it to BNY Mellon, or by calling BNY Mellon directly. A termination will be effective immediately if notice is received by BNY Mellon not less than 10 days before any dividend or distribution record date. Otherwise, the termination will be effective, and only with respect to any subsequent dividends or distributions, on the first day after the dividend or distribution has been credited to the participant’s account in additional shares of the Fund. Upon termination and according to a participant’s instructions, BNY Mellon will either (a) issue certificates for the whole shares credited to the shareholder’s Plan account and a check representing any fractional shares or (b) sell the shares in the market. Shareholders who hold Common Stock registered in the name of a broker or other nominee should consult their broker or nominee to terminate participation.

The Plan is described in more detail in the Fund’s Plan brochure. Information concerning the Plan may be obtained from BNY Mellon at 1-866-351-7446.

Disclosure of Proxy Voting Policies and Procedures for Closed-End Management Investment Companies.

The Proxy Voting Policies are attached herewith.

ADVISER PROXY VOTING POLICIES AND PROCEDURES

Flaherty & Crumrine Incorporated (“FCI”) acts as discretionary investment adviser for various clients, including the following seven pooled investment vehicles (the “Funds”):


As adviser to the “U.S. Funds”		Flaherty & Crumrine Preferred Income Fund Flaherty & Crumrine Preferred Income Opportunity Fund Flaherty & Crumrine Preferred Securities Income Fund Flaherty & Crumrine Total Return Fund Flaherty & Crumrine Dynamic Preferred and Income Fund

As sub-adviser to the “Canadian Fund”		Flaherty & Crumrine Investment Grade Fixed Income Fund

As sub-adviser to the “Mutual Fund”		Destra Preferred and Income Securities Fund

FCI’s authority to vote proxies for its clients is established through the delegation of discretionary authority under its investment advisory contracts and the U.S. Funds have adopted these policies and procedures for themselves

Purpose

These policies and procedures are designed to satisfy FCI’s duties of care and loyalty to its clients with respect to monitoring corporate events and exercising proxy authority in the best interests of such clients.

In connection with this objective, these policies and procedures are designed to deal with potential complexities which may arise in cases where FCI’s interests conflict or appear to conflict with the interests of its clients.

These policies and procedures are also designed to communicate with clients the methods and rationale whereby FCI exercises proxy voting authority.

This document is available to any client or Fund shareholder upon request and FCI will make available to such clients and Fund shareholders the record of FCI’s votes promptly upon request and to the extent required by Federal law and regulations.

Fundamental Standard

FCI will be guided by the principle that, in those cases where it has proxy voting authority, it will vote proxies, and take such other corporate actions, consistent with the interest of its clients in a manner free of conflicts of interest with the objective of client wealth maximization.

General

FCI has divided its discussion in this document into two major categories: voting with respect to common stock and voting with respect to senior equity, e.g., preferred stock and similar securities. In those events where FCI may have to take action with respect to debt, such as in the case of amendments of covenants or in the case of default, bankruptcy, reorganization, etc., FCI will apply the same principles as would apply to common or preferred stock, mutatis mutandis.

These policies and procedures apply only where the client has granted discretionary authority with respect to proxy voting. Where FCI does not have authority, it will keep appropriate written records evidencing that such discretionary authority has not been granted.

FCI may choose not to keep written copies of proxy materials that are subject to SEC regulation and maintained in the SEC’s EDGAR database. In other instances, FCI will keep appropriate written records in its files or in reasonably accessible storage.

Similarly, FCI will keep in its files, or reasonably accessible storage, work papers and other materials that were significant to FCI in making a decision how to vote.

For purposes of decision making, FCI will assume that each ballot for which it casts votes is the only security of an issuer held by the client. Thus, when casting votes where FCI may have discretionary authority with regard to several different securities of the same issuer, it may vote securities “in favor” for those securities or classes where FCI has determined the matter in question to be beneficial while, at the same time, voting “against” for those securities or classes where FCI has determined the matter to be adverse. Such cases occasionally arise, for example, in those instances where a vote is required by both common and preferred shareholders, voting as separate classes, for a change in the terms regarding preferred stock issuance.

FCI will reach its voting decisions independently, after appropriate investigation. It does not generally intend to delegate its decision making or to rely on the recommendations of any third party, although it may take such recommendations into consideration. FCI may consult with such other experts, such as CPA’s, investment bankers, attorneys, etc., as it regards necessary to help it reach informed decisions.

Absent good reason to the contrary, FCI will generally give substantial weight to management recommendations regarding voting. This is based on the view that management is usually in the best position to know which corporate actions are in the best interests of common shareholders as a whole.

With regard to those shareholder-originated proposals which are typically described as “social, environmental, and corporate responsibility” matters, FCI will typically give weight to management’s recommendations and vote against such shareholder proposals, particularly if the adoption of such proposals would bring about burdens or costs not borne by those of the issuer’s competitors.

In cases where the voting of proxies would not justify the time and costs involved, FCI may refrain from voting. From the individual client’s perspective, this would most typically come about in the case of small holdings, such as might arise in connection with spin-offs or other corporate reorganizations. From the perspective of FCI’s institutional clients, this envisions cases (1) as more fully described below where preferred and common shareholders vote together as a class or (2) other similar or analogous instances.

Ultimately, all voting decisions are made on a case-by-case basis, taking relevant considerations into account.

Voting of Common Stock Proxies

FCI categorizes matters as either routine or non-routine, which definition may or may not precisely conform to the definitions set forth by securities exchanges or other bodies categorizing such matters. Routine matters would include such things as the voting for directors and the ratification of auditors and most shareholder proposals regarding social, environmental, and corporate responsibility matters. Absent good reason to the contrary, FCI normally will vote in favor of management’s recommendations on these routine matters.

Non-routine matters might include, without limitation, such things as (1) amendments to management incentive plans, (2) the authorization of additional common or preferred stock, (3) initiation or termination of barriers to takeover or acquisition, (4) mergers or acquisitions, (5) changes in the state of incorporation, (6) corporate reorganizations, and (7) “contested” director slates. In non-routine matters, FCI, as a matter of policy, will attempt to be generally familiar with the questions at issue. This will include, without limitation, studying news in the popular press, regulatory filings, and competing proxy solicitation materials, if any. Non-routine matters will be voted on a case-by-case basis, given the complexity of many of these issues.

Voting of Preferred Stock Proxies

Preferred stock, which is defined to include any form of equity senior to common stock, generally has voting rights only in the event that the issuer has not made timely payments of income and principal to shareholders or in the event that a corporation desires to effectuate some change in its articles of incorporation which might modify the rights of preferred stockholders. These are non-routine in both form and substance.

In the case of non-routine matters having to do with the modification of the rights or protections accorded preferred stock shareholders, FCI will attempt, wherever possible, to assess the costs and benefits of such modifications and will vote in favor of such modifications only if they are in the bests interests of preferred shareholders or if the issuer has offered sufficient compensation to preferred stock shareholders to offset the reasonably foreseeable adverse consequences of such modifications. A similar

type of analysis would be made in the case where preferred shares, as a class, are entitled to vote on a merger or other substantial transaction.

In the case of the election of directors when timely payments to preferred shareholders have not been made (“contingent voting”), FCI will cast its votes on a case-by-case basis after investigation of the qualifications and independence of the persons standing for election.

Routine matters regarding preferred stock are the exception, rather than the rule, and typically arise when the preferred and common shareholders vote together as a class on such matters as election of directors. FCI will vote on a case-by-case basis, reflecting the principles set forth elsewhere in this document. However, in those instances (1) where the common shares of an issuer are held by a parent company and (2) where, because of that, the election outcome is not in doubt, FCI does not intend to vote such proxies since the time and costs would outweigh the benefits.

Actual and Apparent Conflicts of Interest

Potential conflicts of interest between FCI and FCI’s clients may arise when FCI’s relationships with an issuer or with a related third party conflict or appear to conflict with the best interests of FCI’s clients.

FCI will indicate in its voting records available to clients whether or not a material conflict exists or appears to exist. In addition, FCI will communicate with the client (which means the independent Directors or Director(s) they may so designate in the case of the U.S. Funds and the investment adviser in the case of the Canadian Fund or the Mutual Fund) in instances when a material conflict of interest may be apparent. FCI must describe the conflict to the client and state FCI’s voting recommendation and the basis therefor. If the client considers there to be a reasonable basis for the proposed vote notwithstanding the conflict or, in the case of the Funds, that the recommendation was not affected by the conflict (without considering the merits of the proposal), FCI will vote in accordance with the recommendation it had made to the client.

In all such instances, FCI will keep reasonable documentation supporting its voting decisions and/or recommendations to clients.

Amendment of the Policies and Procedures

These policies and procedures may be modified at any time by action of the Board of Directors of FCI but will not become effective, in the case of the U.S. Funds, unless they are approved by majority vote of the non-interested directors of the U.S. Funds. Any such modifications will be sent to FCI’s clients by mail and/or other electronic means in a timely manner. These policies and procedures, and any amendments hereto, will be posted on the U.S. Funds’ websites and will be disclosed in reports to shareholders as required by law.

Item 8. Portfolio Managers of Closed-End Management Investment Companies.

The following paragraphs provide certain information with respect to the portfolio managers of the Fund and the material conflicts of interest that may arise in connection with their management of the investments of the Fund, on the one hand, and the investments of other client accounts for which they have responsibility, on the other hand. Certain other potential conflicts of interest with respect to personal trading and proxy voting are discussed above under “Item 2 - Codes of Ethics” and “Item 7 - Proxy Voting Policies.”

(a)(1) Portfolio Managers

R. Eric Chadwick, Donald F. Crumrine, Robert M. Ettinger and Bradford S. Stone jointly serve as the Portfolio Managers of the Fund. Additional biographical information about the portfolio managers is available in the Annual Report included in Response to Item 1 above.

Potential Conflicts of Interest

In addition to the Fund, the Portfolio Managers jointly manage accounts for four other closed-end funds, one mutual fund, one Canadian fund and other institutional clients. As a result, potential conflicts of interest may arise as follows:

•

Allocation of Limited Time and Attention. The Portfolio Managers may devote unequal time and attention to the management of all accounts. As a result, the Portfolio Managers may not be able to formulate as complete a strategy or identify equally attractive investment opportunities for each of those accounts as might be the case if they were to devote substantially more attention to the management of one account.

•

Allocation of Limited Investment Opportunities. If the Portfolio Managers identify an investment opportunity that may be suitable for multiple accounts, the Fund may not be able to take full advantage of that opportunity because the opportunity may need to be allocated among other accounts.

•

Pursuit of Differing Strategies. At times, the Portfolio Managers may determine that an investment opportunity may be appropriate for only some accounts or may decide that certain of these accounts should take differing positions (i.e., may buy or sell the particular security at different times or the same time or in differing amounts) with respect to a particular security. In these cases, the Portfolio Manager

may place separate transactions for one or more accounts which may affect the market price of the security or the execution of the transaction, or both, to the detriment of one or more other accounts.

•

Variation in Compensation. A conflict of interest may arise where the financial or other benefits available to the Portfolio Manager differ among accounts. While the Adviser only charges fees based on assets under management and does not receive a performance fee from any of its accounts, and while it strives to maintain uniform fee schedules, it does have different fee schedules based on the differing advisory services required by some accounts. Consequently, though the differences in such fee rates are slight, the Portfolio Managers may be motivated to favor certain accounts over others. In addition, the desire to maintain assets under management or to derive other rewards, financial or otherwise, could influence the Portfolio Managers in affording preferential treatment to those accounts that could most significantly benefit the Adviser.

The Adviser and the Fund have adopted compliance policies and procedures that are designed to address the various conflicts of interest that may arise for the Adviser and its staff members. However, there is no guarantee that such policies and procedures will be able to detect and prevent every situation in which an actual or potential conflict may arise.

(a)(3) Portfolio Manager Compensation

Compensation is paid solely by the Adviser. Each Portfolio Manager receives the same fixed salary. In addition, each Portfolio Manager receives a bonus based on peer reviews of his performance and the total net investment advisory fees received by Flaherty & Crumrine (which are in turn based on the value of its assets under management). The Portfolio Managers do not receive deferred compensation, but participate in a profit-sharing plan available to all employees of the Adviser; amounts are determined as a percentage of the employee’s eligible compensation for a calendar year based on IRS limitations. Each Portfolio Manager is also a shareholder of Flaherty & Crumrine and receives quarterly dividends based on his equity interest in the company.

(a)(4) Disclosure of Securities Ownership

The following indicates the dollar range of beneficial ownership of shares by each Portfolio Manager as of November 30, 2013:


Name		Dollar Range of Fund Shares Beneficially Owned*
R. Eric Chadwick		$100,001 to $500,000
Donald F. Crumrine		$100,001 to $500,000
